format string in datetime c# to insert in MYSQL datetime column

A quick/easy method to insert date or datetime into MySQL is to use the format 'yyyy-MM-dd', or datetime as 'yyyy-MM-dd H:mm:ss'.

Try this

DateTime theDate = DateTime.Now;
theDate.ToString("yyyy-MM-dd H:mm:ss");

Make your SQL look like this.

insert into mytable (date_time_field) value ('2013-09-09 03:44:00');

Your line:

string time = Convert.ToDateTime("10-10-2014 15:00:00");

Shouldn't compile.

I can only guess that you don't have DateTime as type of your column in SQL Server, you should modify it to keep DateTime and then pass a DateTime type object, not a string.
